Application filed May is,

sary to eifect the opening of the lock, said padlock being constructed as hereinafter fully described and claimed.

In the drawings, Figure 1 is a side view of the padlock with a portion of the case removed, and showing the hasp locked. Fig.

2 is a longitudinalsection through the case showing the hasp unlocked and raised. Fig. 3 is a sectional planview through the case, taken on the line 3-3 in Fig.1. Fig. 4.

is a cross-section through the case, taken on the line lt in Fig. 2. Fig. 5 is a cross-section through the case, taken on the line 5-5 in Fig. 2. Fig. 6 is a cross-section through the case, taken on the line 66 in Fig. 2.

Fig. 7 is a side view of the key. Fig. 8 is an end view of the key.

The lock is provided with a case 10 which is preferably cylindrical. Heads 12 and ll are secured in the respective ends of the 26 case, and the head 1 1 is provided with a key hole 15.0n the axis of the case, and this key hole has any suitable pivoted cover.

The hasp 9 is hook-shaped, and one end portion 16 is a straight spindle which slides longitudinally and rotates in guide holes 17 in thesides of the case crosswise of its axis. .The other end portion 18.0f the hasp is a straight rod arranged parallel to the spindle 16, and is slidable in a'hole 19 in one side ofthe case crosswise of its axis, when the hasp is rotated to the position shown. The end portion of the spindle 16 is provided with a stop 20 which comes in, contact with the case when the hasp is slid so that the rod 18 is clear of the hole 19. I

A spring chamber 21 is secured to the spindle 16 on the other side of the case'froin the stop 20, and a releasing spring 22 is inclosed in this chamber, and operates auto- 4 matically to slide the hasp to the unlocked position, as shown in Fig. 2. A disk'2 l 'is secured in the case between the spindle 16 and the head 12. A short shaft 25 is journaled in the disk 2 1 and head 12, on the axis of the case, and a combination disk 26 is secured on one end portion of this shaft the releasing spring 1927. Serial No. 192,573.

outside the case. The combination disk. 26 is preferably a cap which fits over the head 12, and it is provided with suitable graduaions which are numbered. The case is provided with a suitable mark or pointer for the graduations, but the disk and case may have any other suitable markings such as used on combination locks.

21 disk 28 is secured in the case on the other side of the spindle 16 from the disk 24:, and an intermediate disk 29 is secured in the case substantially midway between the disk 28 and the key hole head let. A locking bolt 30 is arranged on the aXisof the case, and

is slidable in holes in the disks 28 and 29. A' locking spring 31' encircles the locking bolt 30, and is arranged between the disk 29 and a pin or projection 52 on the locking bolt, and this spring projects thelocking bolt into a hole 33 in the spindle 16, when the said spindle is pushed to the locked position by hand against the pressure of The locking bolt 30 has an operating pin or projection 3 1 which projects crosswise of it, and is arranged between the disk 29 and the key hole head let at a predetermined distance from the key hole.

The locking bolt 30 is prevented from rotating by any suitable means, and 35 are guide pins arranged in pairs parallel to each other between the disk 29 and the key hole head 1 1. A pin 36 projects crosswise of the locking bolt, and projects between the pairs of guide pins, and prevents the locking bolt from rotating, but permits it to slide longitudinally.

A locking shaft 58 is journaled in the heads and disks, to one side of the hasp spindle 16, and parallel to the locking bolt. This shaft 38 is rotated from the shaft 25 of the combination disk 26 by'means of toothed wheels 39 which mesh into each other and are secured on the said shafts. A locking disk 10 is secured on the locking shaft 38 adjacent to the key hole head 14, and has a notch 41 in its periphery, and has also pins 42 which project from one side of it at its periphery. The periphery of the locking disk and its pins l2 are arranged closely adjacent to the locking bolt.

Y and hooks 47 on the end thereof, and the tubular end portion is slidable through the key hole and over the free end portion of the locking bolt. When thenotch ll of the locking disk is opposite the locking bolt, the key can be inserted and slid through the notch, and turned a little around, so that its hooks engage with the operating pin 34.

The locking bolt can then be retracted by the key, so as to free the spindle of the hasp, and the hasp is then slid by its releasing spring 22 to the position shown in Fig. 2. The hasp can then be rotated by hand to open it to the desired extent. The key cannot be inserted to its full extent unless the notch is opposite the locking bolt, because the end of the key strikes the locking disk.

The notch ail is placed opposite the lock ing. bolt by turning the combination disk to indicate the predetermined combination, and the notch cannot be so placed by anyone not knowing that combination. 1 he key is made to lit the'key hole and the locking bolt, and the hasp cannot be unlocked except by a personhaving the correct combination and the proper key.

. The pins 42 on the locking disk prevent the locking disk from being completely rotated when the key is partially inserted in an attempt to find the correct combination by feeling for the notch with the end of the key pressed against the locking disk. The pins l2are arranged to strike the key, and prevent the locking disk from being rotated. sufficiently to place the notch opposite the looking bolt, so as to permitthe key to be inserted to its full extent to engage with the operatmg pin.

What I claim is:

1. In a padlock, a case, a hasp having a spindle which is slidableand rotatable in holes in the sides of the case and having an end portion which interlocks with the case, a locking bolt mounted on the axis of the case and normally engaging withthe said spindle, said locking bolt being provided with a projection for operating it, a locking shaft journaled in the case parallel to the locking bolt, a locking disk secured on the locking shaft with its periphery adjacent to the locking bolt and havinga notch adapted to be placed opposite the locking bolt to permit the insertion of a key to operate the locking bolt, and a combination device arranged outside the case and operatively connected with the locking shaft;
